The federal Conservative government committed $2 billion in incentives for ethanol, made from wheat and corn, and biodiesel in last week's budget.

But based on Ottawa's own research, critics say the investment is based more on myth than hard science.

Scientists at Environment Canada studied four vehicles of recent makes, testing their emissions in a range for driving conditions and temperatures.

"Looking at tailpipe emissions, from a greenhouse gas perspective, there really isn't much difference between ethanol and gasoline," said Greg Rideout, head of Environment Canada's toxic emissions research.

"Our results seemed to indicate that with today's vehicles, there's not a lot of difference at the tailpipe with greenhouse gas emissions."

The study found no statistical difference between the greenhouse gas emissions of regular unleaded fuel and 10 per cent ethanol blended fuel..." (Read the entire article)

So basically my gasoline/ethanol blend that evaporates in the summer's heat has been a complete waste of money and doing nothing to spare the environment to boot...
